Low implantation line double-wire section terminal spine type bearing rail beam limiting structure in medium and low speed magnetic levitation transportation engineering

Abstract

The invention discloses a low implantation line double-wire section terminal spine type bearing rail beam limiting structure in medium and low speed magnetic levitation transportation engineering. The limiting structure comprises bearing rail beam lower subgrade filling, a bearing rail beam underlayer, two adjacent sections of bearing rail beams, vertical slab staggering prevention lapping plates, horizontal slab staggering prevention bosses and a bearing rail beam backfill material, wherein the vertical slab staggering prevention lapping plates are fixedly arranged on the bearing rail beam lower subgrade filling, and the lower ends of the vertical slab staggering prevention lapping plates stretch into the bearing rail beam lower subgrade filling. According to the invention, slab staggering prevention reinforced concrete lapping plates are arranged at bearing rail beam section positions, the bearing rail beam is arranged on the same reinforced concrete slab staggering prevention plate with a certain rigidity, and the problem that the rail surface is unsmooth due to differential settlement of the bearing rail beam lower subgrade is effectively solved.

Description

technical field [0001] The invention belongs to the field of medium and low-speed maglev low-set lines, and more specifically relates to an end-stab type internode space-limiting structure of a low-set line of a medium-low-speed maglev traffic engineering double-track section. Background technique [0002] Medium and low-speed maglev rail transit is a new type of transportation. At present, there are few research results at home and abroad, and there are even fewer lines in operation around the world. At present, there are only the commercial operation line of the medium and low speed maglev railway in Japan in March 2005-Eastern Hills Line and the commercial operation line of the medium and low speed maglev railway in South Korea in June 2014. At present, China's medium and low-speed maglev transportation only has the National University of Defense Technology test line, the Qingchengshan test line, and the Tangshan test line, but there are no official lines in operation, an...

Problems solved by technology

[0004] In order to prevent excessive temperature stress and uneven settlement, the traditional rail-bearing beam structure generally adopts expansion joints of 10-30m per section. Due to the influence of various factors, the quality is relatively difficult to control, so it is easy to produce uneven settlement under the action of load and various natural and various natural factors. It is inevitable that there will be inconsistent post-construction settlement between adjacent rail bearing beams, resulting in the occurrence of Wrong platform, which will affect the smoothness of F track, and may even cause problems such as wrong platform and deformation of F track, which will affect the normal operation of maglev vehicles in severe cases
